To all whom it may concern:

Be it known that I, ALBERT SUEHY, J r, a citizen of the United States, residing at Newark, county of Essex, and State of New Jersey, have invented a newand useful Imp fovement in Machines for Cleaning Plastic aterials, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this-specification.

My invention relates to means for cleaning plastic substances, particularly chicle used in the manufacture of chewing gum.

Heretofore in cleaning chicle and other plastic substances for the removal of foreign substances such as bark and grit, the

method has been to wash the substance with water. Washing has been found ineffective to thoroughly cleanse, and a certain amount product. i

The object of my invention is to provide 'means for the positive removal of foreign in which I have illustrated a matter from plastic substances.

Referring to the accompanying drawings,

preferred embodiment of my invention 1 Figure 1 is a side'elevation, partly broken away, of a machine for cleaning chicleand other plastic substances. I

Fig. 2 is an end view of the machine looking from the right-hand side of Fig. l. F ig. 3 is a plan view, partly in section, of the subject of Figs. 1 and 2. v

. To the frame L is suitably journaled at 9 the shaft 7 which carries the large cylindris'maller rollers Band 6 carried on the shafts 5 and 5" journaled in the sliding blocks 10 and 10 on the'frame, 4 and parallel to the shaft 7. The relative position ofthe rollers 6 and 6 may be adjusted by the screws 11 carried by the auxiliary frame 26 in connection with the slidable blocks in which they are journaled respectively, being provided to effect the desired adjustment. The main shaft 7 is provided with the gear 14 which meshes with-the gear 15 carried "by the driving shaft 16 which carries a pulley 17 for receiving power. ,The arm 20 is ivotedto the auxiliar frame 26 and exten s over the roller 8. A ove the roller, and suitably fasmmed to the arm 20, are scrapers 19 and 19 The scra ers are adjusted to and from the rollerS-by the adjustment of the arm :20 through its rearwardly extending portion 19., and under the spray 27 19 is adjusted toward the surface of the Specification of Reissued'letters Patent. Rissued Ma 8 1921; Original No. 1,247,113, dated November 20, 1917, Serial No. 167,850, filed May v reissue filed March 26, 1920. Serial No. 869,119,

10,1917. Application in in connectionwith the screws21 and 21 The scrapers are also independently adjustable to andfrom the roller. At the front of the roller 8 is suitably mounted in the pivoted holder 23 thescraper 22 which is adsimilar the rollers. The pan 29' is made relatively deep, so that the lower part of the rollers 6 and 6 will revolve in water. The pipe 28 is connected with: a source of heat and, run into the pan 29 to maintain a relatively high temperature in the water. Also branches 28 from the pipe 28 are run into'the hollow cylinders 6, 6 and 8, for heating these cylinders, as shown in Fig. 3. t Q

In practice, after the machine has been set 1n motion, water is sprayed on the rollers through the sprays 27 and 27 Chicle, or other plastic substance which it is desired to clean, which. has been previously heated, issthenffed between therollers 6- and 6' where it is subjected to a stream of water. The'chiole adheres to the rollers and is thoroughly washed by being carried through the heated water in pan 29. The

. chicle which is carried'by the roller 6 comes in contact with and is gradually transferred to the-roller 8 which, traveling in the .direccal roller 8, adjacent to which are the two;

tion of the arrow, carries it to the scraper The scraper roller 8 sufficiently close to prevent the passage beneath it of any but very small particles of foreign matter, thus partially cleaning the chicle. The chicle is then carried by the roller to the scraper 19 which isadjusted to leave only a minute clearance from the surface of the roller. The scraper 19" holds up all the remaining foreign matter. A minute film of cleaned chicle is left on the roller and passes to the scraper 22 which removes it and permits it to drop into the pan 25, where it is collected for use. The chicle which adheres to the roller 6 is'gradu'ally transferred to the roller 6 I v positioned the Water spray nozzle 2Tt'scar ,20 M Y y l @1 1 Ina machine for cleaningplastic subpassed the scrapers under i the infl ui bark, grit, etc.
